Definitions

  • the invention relates to a profile bar and constructed with such a profile bar support bar for a heald.
  • Web shafts usually have two shaft rods, each consisting of a support rod and a heddle rail.
  • the Litzentragschienen serve as a seat for receiving a plurality of healds, sitting with their end loops on the heald bar.
  • the support rod consists of a profile bar, for example in the form of an aluminum extruded profile and other elements, such as steel inserts for connecting side supports.
  • the DE 196 12 404 A1 discloses in particular the corner connection of a heald.
  • the support rod consists of an aluminum extruded profile, which encloses an elongated cavity. At the end of the support rod, a steel insert is mounted in the cavity. This is connected to the aluminum support rod by rivets.
  • a relatively thin-walled profile bar has on its side walls Einsprungzonen that can be used for fastening appropriately shaped profile pieces, in particular by means of riveting are.
  • the side walls of the profiled bar in a small wall thickness while, on the other hand, anchoring points for profile sections to be mounted are created by the entry zones.
  • the entry zones there are parts of the side walls in the cavity defined by them.
  • the profile bar On the outside, the profile bar may be flat, i. be well educated.
  • the entry zones then form zones of increased wall thickness, to which, for example countersunk rivets or countersunk screws can be attached. These are preferably not available over the outer surface of the side wall.
  • the entry zone may also have a strip-shaped depression on the outside of the profile bar. This depression is preferably so deep that in the depression flat head rivets or round head rivets have space for attachment of profile pieces between the side walls.
  • the recess may form a bead and preferably has a flat bottom.
  • the wall thickness in the recess in this embodiment is preferably at least as large as the wall thickness outside the entry zone.
  • the entry zone preferably occupies only a small portion of the height of the side wall.
  • the height is to be measured in a direction parallel to the side wall and thereby transversely to the profile bar. In the installation position of the heald, this height direction extends vertically.
  • the width of the entry zone occupies at least five and at most twenty-five percent of the width of the sidewall.
  • the profile bar is preferably formed as a light metal extrusion profile, for example made of aluminum or an aluminum alloy. He can do it seamlessly in one Piece and are made endless and will be cut to appropriate lengths if necessary. It then consists of a uniform material and is integrally formed.
  • the profile bar can be obtained by assembling a plurality of parts, such as sheet metal parts, strips, rods and the like. These parts can be made of steel, light metal, plastic, fiber reinforced plastic and the like and, for example, welded together, glued or otherwise assembled and connected together.
  • the inventive concept is suitable both for connection of profile pieces, for connecting side supports as well as for the cultivation of profile pieces for the connection of center connectors, drive plates, hooks or other parts on a heald.
  • FIG. 1 a heald 1 is illustrated, which has an upper shaft rod 2, a lower shaft rod 3 and side supports 4, 5, which together form a rectangular frame.
  • the side supports 4, 5 have terminals 6, 7, which are to be connected to a drive device of the loom.
  • they are provided with extensions which are inserted into correspondingly reinforced ends 8, 9, 10, 11 of the shaft rods 2, 3 and fixed there.
  • the shaft rods 2, 3 also have Litzentragschienen 12, 13, which serve to receive the healds.
  • FIG. 2 illustrates the shaft rod 2, the structure of which is identical to the structure of the shaft rod 3 in principle.
  • the shaft rod 2 comprises a support rod 14 and a heddle support rail 12.
  • the latter is for example a profiled steel rail which is suitably detachably or permanently connected to the support rod 14, for example by riveting, gluing, welding, clamping or the like.
  • the support bar 14 is formed from a profile bar 15 and profile pieces 16, 17, which are attached to the profile bar 15.
  • the profile bar 15 is preferably formed by an aluminum extruded profile. This has two preferably spaced parallel to each other oriented side walls 18, 19, along the profile bar 15 in bar longitudinal direction (in FIG. 2 perpendicular to the plane of the drawing) and thus extend parallel to the heddle support rail 12 and are oriented horizontally in use.
  • the height of the side walls 18 and 19 is in FIG. 2 indicated with b2 and may vary in size.
  • the side walls 18, 19 are connected to each other by webs 20, 21, 22 and enclose at least one or more cavities 23, 24.
  • the side walls 18, 19 are particularly outside substantially flat (preferably flat) formed.
  • entry zones 25 to 28 are preferably strip-shaped regions which extend over the entire length of the profile bar 15.
  • the height of the entry zones 25 to 28 is in FIG. 2 indicated b1 and may be 5% to 25% of the height b2 of the side wall 18, 19.
  • these entry zones 25 to 28 are preferably not in direct contact with the webs 20, 21, 22 but spaced therefrom.
  • the entry zones 25 to 28 are characterized in that the side wall 18, 19 projects into the relevant cavity 23 or 24.
  • This can, as in FIG. 2 indicated, can be achieved by the side walls 18, 19 have sections which are arranged offset in cross section parallel to the side walls 18, 19 slightly to an imaginary vertical center plane of the profile bar 15 towards.
  • this may be how it is in FIG. 3 is indicated, be achieved in that the wall thickness of the side walls 18, 19 is increased in the entry zones 25 to 28.
  • the profile bar 15 after FIG. 2 Partial cross section shows.
  • the side walls 18, 19 may be mirror-symmetrical to each other. The following description of the side wall 18 therefore applies correspondingly to the side wall 19.
  • the side wall 18 has an inner side 29 and an outer side 30. Both the inside 29 and the outside 30 can, except for the entry zone 25, be flat. Between the inner side 29 and the outer side 30, the wall thickness W1 of the side wall 18 is to be measured. In the entry zone 25, the wall thickness W2 is to be measured between the relevant inner side 29 'and 30'.
  • the wall thickness W2 preferably coincides with the wall thickness W1; possibly It can also be sized larger or smaller.
  • the entry zone 25 forms in this embodiment, such as FIG. 4 shows, an outwardly open flat recess, for example in the form of a groove whose bottom is formed by the outer surface 30 '.
  • the distance of this bottom 30 'from the plane defined by the outer surface 30 forms the depth T of the entry zone.
  • this depth T is greater than the wall thickness W1.
  • the profile bar 15 can be formed both as an extruded profile and constructed from one or more sheet metal parts.
  • the side walls 18, 19 may be sheet metal parts.
  • the profile piece 16, 17 on its two sides on shallow grooves which can accommodate the protrusions formed by the entry zones 25, 26, 27, 28.
  • the side surfaces of the profile pieces 16, 17 complementary to the inner surfaces of the side walls 18, 19 are formed.
  • the profile pieces 16, 17 may be the same or different. However, they each have at least one, preferably in the transverse direction from one side wall to the other side wall through holes, which serve for receiving fasteners, for example in the form of rivets 31, 32.
  • the fastening means 31, 32 are, for example, round or flat head rivets whose heads 33, 34 have a height that is less than the depth T (according to FIG FIG. 4 ). This also applies correspondingly to the round heads 35, 36 formed at the respective other end of the respective rivet 31, 32. Other fastening means such as screws may also be used.
  • the profile pieces 16, 17 can, as FIG. 1 indicates to be formed on legs of the profile bar 15 and between take each other a projection of the side support 4. For a robust corner joint is created, which also allows the introduction of high forces in support rods 14, which have very thin side walls with a wall thickness W1 of eg less than one millimeter.
  • the arranged by the webs 20, 21, 22 spaced Einsprungzonen 25 to 28 may also have a wall thickness W3, which is significantly greater than the wall thickness W1.
  • the outer surface 30 can be flat overall, ie in particular in the region of the entry zone 25 without a depression.
  • the increased wall thickness W3 allows the installation of countersunk rivets, as in FIG. 5 indicated by dashed lines.
  • Such a countersunk rivet 31 ', 32' terminates flush with the outside 30 or even forms a small depression.
  • FIG. 6 shows to form a strip-shaped recess with a wall thickness W4, which is smaller than the wall thickness W3. It can be greater or smaller than the wall thickness W1 or agree with it.
  • the profile pieces 16, 17, 37 consist of steel.
  • the profile piece 37 may be provided for receiving the threaded plate 39, for example, with a T-groove. Due to the large-scale attachment of the profile piece 37 in the cavity 24 of the profile bar 15 by means of a plurality of rivets 38 creates a mounting option for the intermediate strut and the middle connector 40, which is much higher load than previously known solutions.
  • riveted or screwed profile pieces can continue to serve for the attachment of coupling elements, which establish the connection between Webschaft and its drive means.
  • coupling elements which establish the connection between Webschaft and its drive means.
  • here are called Glashaken, which are connected to traction cables or return springs negative acting dobby.
  • a preferably made of extruded aluminum profile bar 15 has side walls 18, 19, the two mutually projecting, parallel to each other preferably over the entire length of the profile bar 15 extending and arranged at the same height Einsprungzonen 25, 26 has.
  • the distances between the two entry zones 25, 26 from the nearest web 21 coincide with one another.
  • the profile bar 15 on the one hand be formed very thin-walled, on the other hand, he offers opportunities to attach profile pieces that allow the entry and exit of larger forces in the section bar 15.
  • This concept provides a basis for the construction of lightweight but highly resilient heald frames.
